Telltale Games releases mysterious teaser trailer

Telltale Games has recently released a mysterious trailer showing characters from Sam & Max, Penny Arcade, Strong Bad and... Team Fortress 2(?) and asking what they have in common.

Speculation amongst the fans indicate it may be a new Telltale Poker game (which is a bit of a letdown) but likely to be the outcome (you can almost make out them holding cards from their silhouettes).
